Type Identity  & Mass Probability  & Std. Error \\

\footnotesize Notes: Bootstrap standard errors in parentheses. Type dummy labels are as follows: ``H'' signifies ``high type''; ``L'' signifies ``low type''. Labels are ordered as \{ Schooling ability, Schooling preferences, Work motivation \}. e.g. ``Unobserved type (H, L, H)'' corresponds to a worker with high schooling ability, low schooling preferences, and high work motivation.  Labels are identified through the measurement system detailed in Appendix \ref{App:meas-sys-appendix}.
